CXA1511M

CXA1511L/M Preamplifier for Remote Control Signal Reception Description The CXA1511L/M is a bipolar IC used for preamplifiers that receive signals in infrared remote control systems. These ICs consist of a first-stage amplifier, limiter amplifier, band-pass filter, band elimination filter, signal waveform detection circuit and waveform shaping circuit. Features Low power consumption (VCC = 5V, 9mW typ.) Low supply voltage (VCC = 5V) Filters (center frequency can be varied through external resistor: fo = 30kHz to 60kHz, 40kHz typ.) Elimination of inductors prevents magnetic field inductance interference. Optical reception diode can be coupled directly. Collector output (pull-up resistor, TTL and CMOS can be connected directly) Applications TVs, VCRs, audio equipment Structure Bipolar silicon monolithic IC Block Diagram and Pin Configuration 8 pin SIP (Plastic) 8 pin SOP (Plastic) Absolute Maximum Ratings 7 V Supply voltage VCC Operating temperature Topr –20 to +75 °C Storage temperature Tstg –65 to +150 °C Allowable power dissipation PD 600 mW (SIP) Allowable power dissipation PD 300 mW (SOP) Operating Conditions Supply voltage 4.7 to 5.3 V Head Amp IN 1 ABLC Photo Diode Limiter Amp BPF Delector & Hysteresis BEF Comparator Integralor Comparator 2 C1 470, 680 0.01µ 3 4 5 6 C2 GND fo N.C. 7 8 OUT VCC 0.01µ 200k (fo = 40kHz) VCC = 5V Sony reserves the right to change products and specifications without prior notice.
